Getting Rid of Black Algae – For Good

If you notice black spots beginning to crop up on your swimming pool surfaces – particularly in places that are difficult to reach, like corners and steps – black algae might be the culprit. This particularly aggressive algae is difficult to treat for two reasons:

  • It has deep roots that help it to firmly embed in surfaces
  • Its outer protective layer is difficult for pool chemicals to penetrate

Yuck! That doesn’t sound like good news. But don’t despair; we’re on your side, and we can show you how to get rid of black algae. More importantly, we can teach you how to keep it from coming back.

How to get rid of black algae. This job will require some vigorous scrubbing. Use a tough, sturdy nylon brush, and don’t be afraid to work up a sweat. You have to break past that protective layer, and remember that embedded roots may still be present even if the spots seem to disappear.

Your next step is to use a chlorine tablet to directly scrub at the spot. This can help to kill the roots so that the algae doesn’t come back. Make sure to wear gloves and a mask, to protect yourself.

Now, clean out your pool’s filter. Black algae is more likely to return when your pool water is in less than pristine condition.

Remove all pool toys and other objects, and clean them thoroughly with bleach and water. You want to kill any algae spores that they might be harboring, or else they will just reintroduce the algae to your pool. The same goes for your swimsuits; make sure to wash them regularly.

Consider shocking your pool. Shocking your pool can be a serious step, so we recommend that you contact us first. It might be necessary, especially if you have been battling a black algae problem repeatedly.

Preventing black algae. Like most things, prevention of black algae is preferable to the “cure” once the problem has occurred. You can prevent black algae from invading your pool by practicing a meticulous pool maintenance routine. This will involve regular pH and chemical tests, necessary adjustments to the pH and chemical levels, regular scrubbing and vacuuming, running the pump and cleaning the filter.

Yes, that sounds like a lot of work! But if you’d rather spend your time enjoying your pool, instead of scrubbing at algae stains, give us a call. We can take over the maintenance for you, so that you can relax and know your pool is in good hands.
